Well i found what i believe to be an old doorknob and was hoping you could help me understand exactly how old it is and where it may have been used.I believe its a steel base with galvanized handle with wooden grips. Across the top it has DEP. and along the bottom has 314. The middle has the initials H R along with decorative flowers. The under part has some letters but can barely make them out, i think it reads GR 20 R, but im not sure about that 20.
